Usually it comes in the form of an involuntarily, physical action. The way their left eye twitches or their lips quiver or how they can't look at you in the eye. Each explain an emotion that you can't or rather, don't wish to tell. When people find out your tell tales, it can be a good thing at times but sometimes it can feel like you just gave a secret of yours by accident. Tell tales are the worst in poker.
You know how animals have a 6th sense so that when they sense danger, like an earthquake, they know it's coming and run away to safety. When it comes to me, and I see all the tell tales sign that my friend is getting ready to blow up, instead of running for cover, I like to stay, survive through all the destruction and find out what's going on. I've noticed maybe a year ago that my fault is that when there's a conflict, for some reason I always seem to have the need to play devil's advocate. I always try to get them to see the other side because I see reason in it when in reality sometimes a person just needs be listened to and to have me side with them in everything, despite my opinion. It's part of comforting, it's part of being a good friend. The trick is learning how to discern the situations that call for different things because sometimes your friend needs to hear the truth. And there are the times, that they don't need to at the moment. Cause if I was in some situation where I was really sad or angry, i'd like my friend to back me up rather telling me other things, just to blow off some steam, you know? Some things don't call for rationality just yet. In the end though, the right choices must be made.
It's good to get things written out, it soothes the mind and soul.
